If an irregularly shaped object (such as a wrench) is dropped from rest in a classroom and feels no air resistance, it will:

a) accelrate and turn about its center of gravity with uniform angular accelration.

b) accelrate and spin until its center of gravity reaches its highest point.

c) accelrate and turn until its center of gravity reaches its lowest point.

d) accelrate and turn about its center of gravity with uniform angular speed.

e) accelerate but will not spin.
